CVE-2026-1780 describes a reflected Cross-Site Scripting vulnerability in the [CR]Paid Link Manager WordPress plugin by silentwind, affecting all versions up to and including 0.5. The issue is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of URL path parameters. This allows unauthenticated attackers to inject malicious scripts that execute in the context of users who click on crafted links, potentially leading to information disclosure or session manipulation. The vulnerability has a CVSS 3.1 base score of 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity with no impact on availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser, potentially resulting in information disclosure or manipulation of user sessions. The vulnerability requires user interaction (clicking a malicious link) and does not require authentication. There is no direct impact on system availability. No known exploits have been reported in the wild.

No official patch or remediation is currently available for this vulnerability. Users of the [CR]Paid Link Manager plugin should monitor the vendor's channels for updates or patches. As a temporary mitigation, administrators may consider disabling or removing the plugin until a fix is released. Additionally, exercising caution with untrusted links can reduce risk.
